Well it's a bit more than a pebble but I've already shot THE Rock.
This is a large round rock on the beach at Elgol that I first saw when Paul (sut68) posted it in 2010 and made reference to some ice cream man who is supposed to have bagged it first.
I turned up one evening and a photographer had already claimed the zone (we joked about ticket systems!) so I had to come back the day after.
I love the rock and the shapes around so decided to follow the tripod holes here too. And, as if by magic, the surrounding platforms (sloping rocks) do appear to have tripod holes. Good job because to get to certain angles (not this one) you do have to do some jiggery pokery with the tripod legs. I was thankful to the versatile Manfrotto Neotec.
I took the Strobeam flash with the plan to illuminate the rock and surrounds while exposing for the background but the flash wasn't strong enough to do what I wanted. I also used the Lee 0.9 ND grad but that wasn't strong enough to cope with the contrast range. So HDR or some more jiggery pokery? I chose the latter and used the Lee Filters grad case to act as a mask . Exposed for the foreground and wafted the filter case over the top half to dumb down the sky.
I ended up with a RAW file that can be processed very differently and settled on this warm version.
